Better, form (by weight percentage) by following component:
Polyphenylene sulfide 15--20%, tetrafluoroethylene 10--28%, chromium sesquioxide 5--8%, cobalt sesquioxide 4--10%, moly-sulfide 8--10%, titanium dioxide 12--14%, ethanol 16--30%, water 4--6%.
Preferably, form (by weight percentage) by following component:
Polyphenylene sulfide 20--25%, tetrafluoroethylene 10--25%, chromium sesquioxide 10--12%, cobalt sesquioxide 7--8%, moly-sulfide 6--12%, titanium dioxide 10%, ethanol 5--7%, water 7--16%
The preparation method of above-mentioned polyphenylene sulfide (PPS) modified paint comprises the steps:
1) gets polyphenylene sulfide, tetrafluoroethylene, chromium sesquioxide, cobalt sesquioxide, moly-sulfide, titanium dioxide by described weight ratio, in mixing tank, mix;
2) material that mixes is ground in milling apparatus, make 300-500 purpose micro mist;
3) micro mist after will grinding places mixing tank, adds dispersion agent second alcohol and water by described weight ratio, mixes, and becomes suspension.
Above-mentioned polyphenylene sulfide (PPS) modified paint is used for making the composite bed with corrosion-resistant, high temperature resistant, high insulation, high strength, impact resistance on the wall of metal products.Metal products can be metal tube or plate or various shaped piece.
Method with above-mentioned polyphenylene sulfide (PPS) modified paint is made composite bed on the wall of metal products comprises the steps:
1) surface derusting, the degreasing of metal products is also dry;
2) the polyphenylene sulfide modified paint evenly is sprayed on the metal products surface, coat-thickness 50-500 μ m;
